1500 years later, Marie Curie's notebook still had no radiation

Almost 100 years after Marie Curie died, many of her personal belongings were still contaminated with radiation. Visitors who want to see Marie Curie's manuscript in the library in person must wear a suit because they will continue to be contaminated for more than 1500 years.

Marie Curie's handbook is still contaminated with radiation until now

Marie Skłodowska-Curie (November 7, 1867 - July 4, 1934) was a Polish-French physicist and chemist, famous for her pioneering research in radioactivity. She was the first person to be honored with two Nobel Prizes in two different fields, physics and chemistry.

Marie Curie and her husband, Pierre Curie, jointly developed the research results of French physicist Henri Becquerel, that uranium is radioactive. By 1898, she and her husband found a new radioactive element. The duo named the element 'polonium' , similar to the word Poland (Poland) - the homeland of Marie Curie.

However, after more than 100 years, many of Marie Curie's personal belongings including clothes, furniture, cookbooks, and laboratory notebooks are still contaminated with radiation.

Marie Curie's handbook - a treasure of world science - is currently stored in a lead box at the French national library. It is known that this book is contaminated with radioactive Radium 226 and has a half-life of 1,600 meters (ie after 1600 years, this amount of radioactive material will be halved compared to the original).

All visitors who want to see this book with their eyes will have to sign the paper to take full responsibility for any incident (if any) and will have to wear a tight protective clothing.

Marie Curie died of aplastic anemia (blood cannot be regenerated due to radiation). At work, Marie Cuire often conducted tests with tubes containing radioactive isotopes in a pocket, preventing the table.

For a long time working with radiation without any safety measures, she was exposed to radiation poisoning.

Her body is still contaminated with radiation and placed in a coffin with 2.5cm thick layers of lead inside to prevent radioactivity from spreading to the surrounding environment.
